SOLDERING-MAGHINE.

T o all whom it may concern:

Be it known that I, CHARLES W. GRAHAM, residing at Rome, in the county of Oneida and State of New York, have invented certain new and useful Improvements in Soldering-Machines, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to soldering machinery.

One of the objects thereof is to provide highly eiiicient machine of simple construction adapted to apply solder with a maximum of thoroughness and reliability in action.

Another object is to provide means of the above type in which the seam is successively exposed to a series of solder-applying means and the solder thoroughljT sweated therein.

Another object is to provide a soldering machine in which the articles to be soldered may be fed with small power and no chance of injury thereto.

Other objects will be in part obvious and in part pointed out hereinafter.

rlhe invention accordingly consists in the features of construction, combinations of elements and arrangement of parts which will be exemplified in the machine hereinafter described and the scope of the application of which will be indicated in the following claims.

In the accompanying drawings wherein is shown one of various possible embodiments of my invention: Figure l represents a sectional elevation of the same taken on the line 1 1 of Fig. 3. Fig. 2 is a similar view taken at right angles to Fig. l on the line 2 2 of Fig. l. Fig. 8 is a side elevation of the complete machine. Fig. t is a detailed sectional view of a propelling spring.

Similar reference characters refer to similar parts throughout these several Views.

In order to render clearer the general nature of my invention, it may first be noted that in machinery of the t-ype with which this invention deals, if the solder be quickly applied and left without further treatment, it is not thoroughly forced into the joint. Nevertheless, on account of the small selling price of the single finished article, it is nec- Specification of Letters Patent.

essary that the same be soldered at a comparatively high rate of speed in order to preserve the desired economy in product-ion. It may also be noted that if the article to be soldered is continuously subjected to the pressure of comparatively rigid solder-applying means, the power required for such feeding is considerable. The above and other defects are removed in constructions of the nature of that hereinafter described.

Referring now to the drawings, there is shown a tank or receptacle l which may be formed of any suitable material adapted to hold molten solder, and if desired, it may be provided with heat-applying means of a well known type. Journaled within the end walls 2 and 3 are two shafts t and 5, the former of which bears upon its outer projecting end a spur gear 6 by which power may be applied to drive the same. Shaft t is provided with a series of sprocket wheels which in this case take the form of hexagonal pulleys. Upon shaft 5 are round pulleys 8, each of which is adapted to co-act with a corresponding sprocket wheel 7, as is indicated in Fig. l of the drawings. Mounted upon sprocket wheels 't' and the co-acting pulleys S are a series of double chains 9, the links of which each correspond in length with one of the faces of the sprocket wheel. Secured to each of these chains, as by a pivotal connection with alternate joints thereof as indicated in Fig. l, are a series of solderapplying blocks l0, each of which is substantially equal in length to two of the links of the chain. Blocks l0 are preferably arranged in two series substantially as shown, there being an intervening portion of the chain upon which no block is secured; proportions of the lengths of chain upon which blocks are secured to those parts thereof free from blocks being preferably substantially that shown. The reason for this construction will be hereinafter set forth more in detail.

Mounted above receptacle or tank l is a support or carrier 1l which preferably comprises the vertical webs 12, having formed thereon side flanges 18 and having secured to their lower depending portions the straps let, the outer ends of these webs, flanges and straps lying substantially within the surface of the cylinder, as is indicated in Fig. 1 of the drawings. Secured to one of these webs 12, in any desired manner is a strip 15 provided with a depending edge adapted to engage and serve as an abutment for the scam 16 in a can body 17 or other article to be soldered.

The means for feeding the several can bodies along carrier 11 are preferably as follows: Fixed to shaft 4 is a spur gear 18 adapted to intermesh with an idle gear 19 mounted upon the end wall of tank 1 and..

meshing with a spur gear 20 upon a counter shaft 21 journaled within a bracket 22 secured to the bottom of the tank. Upon the remaining end of counter shaft 21 is a bevel gear 23 adapted to mesh with a similar gear 24 upon the shaft 25 of a crank disk 26 journaled upon arm 27 of bracket 22. Crank pin 28 xed in the inner surface of crank disk 26 is adapted to travel in a slot 29 formed in a swinging lever 30 preferably pivoted as at31 to the side wall of the tank. Mounted upon tank 1 as by brackets 32 is a sliding feedrod 33 provided with an outwardly lextending rigid arm 34 having a slotted depending end 35 in which a pin 36 fixed in the upper end of lever 30 is adapted to travel. Tit-hin the face of feed rod 33, which is toward the carrier 11, are formed a series of recesses 37 best shown in Fig. 4 of the drawings, in which are fixed spring 38, the same being below the outer surface of the feed rod, except at their free blunt ends 39., which are adapted to engage and propel the can bodies.

It may here be noted that the word solder is used throughout this specification and the following claims in a broad sense as denoting any adhesive material adapted to join two meeting portions of an article or articles. 1t may also be noted that although this machine is peculiarly adapted to soldering the longitudinal seams of can bodies, it is nevertheless well suited for applying solder, using the term in the above broad sense, to various types of articlesV and 1 desire it to be understood that the following claims are intended to cover such application of my invention.

The operation of the above-described embodiment of my invention is as follows: Assuming that a series of can bodies or other articles to be soldered are positioned upon the carrier 11, as shown in Fig. 2 of the drawings, the shaft 4 is driven as by spur gear 6, thus driving the several chains 9 and sliding the solder-applying blocks 10 in contact withthe superposed seams 16 of the can bodies. The direction of travel of these blocks is such as to force the seam 16 into engagement with the strip 15, the latter thus preventing the rotation -of the can body and olding the seam in such position as to be acted upon by the blocks with a maximum of efciency. The movement of shaft 4 rotates crank disk 26 by means of the abovedescribed gearing, in such direction as to cause a swingin motion Vof the lever 30 which will be rapid in the direction in which the cans are to be fed and comparatively slow in the opposite direction, owing to the relative positions of the shaft 25 and the pivot 31. This swinging movement of lever 30 causes a reciprocation of the feed rod 33 .which will be, as above indicated, comparatively rapid in the direction of feed and with a slow return. Blocks 10 arey so positioned upon chains 9 and are of such length as to contact the corresponding seam during the return of the feed rod 33, at which time the can bodies are stationary, the feed springs being compressed by and slipping past the same owing to the engagement therewith of the inclined portions 40 of the springs. Vhen the blunt free ends 39 of the several springs have reached positions to the rear of the corresponding can bodies, the same snap out so as to project within the path of travel of the bodies and, upon being moved in opposite direction, will engage the rear surfaces thereof and feed them with a comparatively quick movement, the blocks 10 being so positioned as to be free from engagement with the corresponding bodies at the time of feed.

It will thus be seen that 1 have pro-vided a soldering machine of simple and inexpensive construction and et capable of performing thoroughly eflicient work with a high degree of speed. 1t will also be seen that each can body is subjected to the action of a series of solder-applying means, each successive contact sweating the solder further into the seam and tending to perfect the joint. Also, on account of the transverse movement of the solder-applying means the can being prevented from rotating as above described, the solder is thoroughly driven into the joint. It will also be seen that the above described embodiment of my invention is free from complicated mechanism and thus well adapted to stand hard practical use without the necessity for repair or renewal of the several parts.

As many changes could be made in the above construction and many apparently widely different embodiments of my invention could be made without departing from the scope thereof, I intend that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense. Y

I desire it also to be understood thatthe language used in the following claims is intended to cover all of the generic and specic features of the invention herein described and all statements of the scope of the invention, which as a matter of language, might be said to fall therebetween.
